Page 1 of 10
This article describes how to use some useful MOAB commands and how to submit different types of jobs to the MOAB scheduler at the FSU HPC. Don't forget to also read the FAQ on Running jobs on the cluster.
MOAB Command Reference
The following is a list of the frequently used MOAB commands.
- list the jobs in the current queue
- msub -q
- submit a job to the moab batch queue. If no queuename is specificed then the default queue is used. The job submission script is required. Use msub --help to see the full list of options. msub returns the jobid.
- checkjob [-v] jobid
- This command allows users to check their job in the event of problems with the job. This command will show you the reason why your job didn't start if it has been deferred or blocked.
- shows the job submission history statistics.
- cancels a job, takes as an argument the jobID. As a last resort, you can also use mjobctl -C jobID or /opt/torque/bin/qdel jobID if canceljob gives an error.
- gives an estimate of when your job will start to run. Since many people don't indicate the predicated run time of their jobs, this estimate can be completely wrong.
- show the available system resources
See the cluster resources Command Overview page for more information about each individual command.
